I'm probably not the right guy to help on what's what in the MU collection, but I can tell you that Vision is ridiculously expensive right now in a non-phasing form. The phasing Vision, reputedly the variant, is much more common and can be had for $10-12 on ebay. The regular is in a revision case from EE and maybe some of your other wants are in that case pack, but it was backordered the last time I checked.

I don't think the following have been made, but others can correct me:Scarlet WitchHerculesBeastShe-HulkTigraStar Fox

I don't think Wasp has been made in a full size figure as yet either.

Hawkeye has two versions - single carded dark Hawkeye and in a comic pack. Depends what you want. I have both, don't need both so if you don't care I can check what I prefer and you can have the other.

The rest, except for Giant Man have been single carded I think (Wonder Man is only coming in the two pack some time down the line but with Quicksilver, so that's nice). The Giant Man was in a two pack that was an exclusive I think.
